Abstract

Data are presented for the effects of wet and dry grinding on dickite from Ouray, Colorado. With increase in dry grinding time the endothermic d.t.a. peak becomes broader and moves towards a lower temperature, while the exothermic reaction is greatly sharpened. Weight loss data, demonstrate greater water loss from ground material and over a longer temperature range. X-ray powder photographs show that after a relatively short period of grinding little further destruction of the lattice occurs, and this lattice destruction apparently proceeds only to a certain stage, for high order spacings of hkl are very persistent.
